Question

find the value of the expression 5a square b + 2ab square + ab, when a= 0 and b = -1​

Answer 1

Answer:

as a=0 and b=1

5a=5×a square

= 5×1=5

2ab= 2×a×b square =2×1×0=0

ab=a×b=0×1=0

ans 5+0+0= 5

Answer 2

Answer:

0

Step-by-step explanation:

$5a^{2} + 2ab^{2} + ab$

There is no like term, so we will put values a=0 and b= (-1)

$5(0)^{2} + 2(0)( - 1^{2} ) + (0)( -1)$

$0 + 0 + 0$

when we multiply any number with zero we get 0

$0$

Hence, our answer is 0
